Parameter set 1 defective

What does PR1 mean?

This fault specifically indicates that user-defined parameter set 1, stored in the drive's memory, has become corrupted or is invalid. By default, this condition is configured as a Warning, meaning it alerts the operator and is logged, but it does not immediately inhibit pulses. Using a defective parameter set can lead to improper drive operation or damage.

• Corruption of the internal memory block storing parameter set 1.
• Interruption during the saving process of parameter set 1 (e.g., power loss while writing P9-98 = 1).
• Attempting to load a parameter set 1 that is incompatible with the current drive's firmware version.
• Degradation or failure of the drive's non-volatile memory associated with parameter set 1.

Click steps to track your progress.

1. 1

   Attempt to load an alternative, known good parameter set (e.g., switch to parameter set 2 using P0-02 = 2).

2. 2

   Try to reload parameter set 1 from an external backup file using the drive's configuration software.

3. 3

   Manually re-enter critical parameters for set 1, starting with motor data (e.g., P1-01, P1-02, P1-03).

4. 4

   Execute a factory reset specific to parameter set 1 if available, or reset all parameters (P9-97 = 1) and rebuild set 1.

5. 5

   Save the currently active parameter values as a new parameter set to overwrite the corrupted area (e.g., P9-98 = 1).
